Older jars with zinc and plastic lids
I found some old ball perfect mason jars with the old zinc and plastic lids.
I found that the regular mouth jar rings fit on them.
Question is, would any of you use them for canning? Or should I save them for other uses?
I notice that the glass around the rim of the jar is pretty thick. These jars are kinda neat in that the bottoms are somewhat square.
I would be totally into them for dry storage if the mouths were wider but since they are regular mouth, they are not as convenient for such use.
